 is to pour water over the head of the person to be baptized. You can't baptize yourself, by the way. But you don't even need to be baptized by a Christian. Did you know that? If two guys are soldiers in combat and somebody's bleeding to death and he's telling his atheist friend or Muslim friend, Hey, I'm a Christian. I've never been baptized before I bleed to death. Would you baptize me? Take my canteen.
